Nursing Elites

1. A nurse in a clinic is caring for a client who came to be tested for tuberculosis (TB) after a close family member tested positive. The nurse should know that which of the following is a diagnostic tool used to screen for TB?

• A. Sputum culture for acid-fast bacillus (AFB)
• B. Mantoux skin test
• C. BCG vaccine
• D. Chest X-ray

Correct answer: B

Rationale: The Mantoux skin test, also known as the tuberculin skin test, is a diagnostic tool used to screen for tuberculosis (TB). It involves injecting a small amount of tuberculin under the top layer of the skin on the forearm and then checking for a reaction within 48-72 hours. This test helps identify individuals who have been exposed to the TB bacteria. Sputum culture for acid-fast bacillus (AFB) is used to confirm TB diagnosis in individuals suspected of having active TB. The BCG vaccine is used to prevent severe forms of tuberculosis in high-risk individuals but is not a diagnostic tool. While a chest X-ray can show signs of active TB disease, it is not a primary diagnostic tool for screening purposes.

2. A nurse at a provider's office receives a phone call from a client who reports unrelieved chest pain after taking a nitroglycerin (Nitrostat) tablet 5 minutes ago. Which of the following is an appropriate response by the nurse?

• A. Tell the client to take an aspirin.
• B. Instruct the client to call 911.
• C. Have the client take another nitroglycerin tablet in 15 minutes.
• D. Advise the client to come to the office.

Correct answer: B

Rationale: In this scenario, the client reporting unrelieved chest pain after taking a nitroglycerin tablet could be indicative of a serious cardiac event. Instructing the client to call 911 is the most appropriate response because immediate medical attention is necessary for chest pain that is not relieved by nitroglycerin. Telling the client to take an aspirin (Choice A) may not address the urgency of the situation, and aspirin might not be appropriate depending on the client's medical history. Having the client take another nitroglycerin tablet (Choice C) without relief could lead to overdosage. Advising the client to come to the office (Choice D) is not the best course of action when dealing with a potential cardiac emergency that requires immediate intervention.

3. A client with chronic obstructive pulmonary disease (COPD expresses difficulty in bringing up bronchial secretions. Which action should the nurse take to help the client with tenacious bronchial secretions?

• A. Maintaining a semi-Fowler's position as much as possible
• B. Administering oxygen via nasal cannula at 2 L per min
• C. Helping the client select a low-salt diet
• D. Encouraging the client to drink eight glasses of water daily

Correct answer: D

Rationale: Encouraging the client to drink eight glasses of water daily is the most appropriate action to help with tenacious bronchial secretions in COPD. Increased fluid intake can help in thinning the mucus, making it easier for the client to cough up and clear secretions. This addresses the client's difficulty in bringing up bronchial secretions. Maintaining a semi-Fowler's position can aid in breathing but does not directly address the issue of clearing secretions. Administering oxygen may be necessary for COPD, but it does not specifically target the tenacious secretions. Selecting a low-salt diet can be helpful in managing COPD in general, but it does not directly address the client's current concern of clearing bronchial secretions.

4. A client who is HIV-positive, has pneumonia and is not responding to antibiotic therapy may have active pulmonary tuberculosis (TB) due to exposure history and symptoms of night sweats and hemoptysis. Which test is the most reliable to confirm the diagnosis of active pulmonary TB?

• A. Chest x-ray
• B. Presence of bronchophony
• C. Mantoux test
• D. Sputum culture for acid-fast bacillus

Correct answer: D

Rationale: The correct answer is D: Sputum culture for acid-fast bacillus. The most reliable test to confirm the diagnosis of active pulmonary TB is the sputum culture for acid-fast bacillus. This test helps identify the presence of Mycobacterium tuberculosis, the causative agent of TB, in the sputum. Chest x-rays can show characteristic findings of TB but are not as reliable as sputum cultures for confirmation. Bronchophony is a test for assessing vocal resonance and is not specific for TB diagnosis. The Mantoux test is a screening test for TB exposure but cannot confirm active disease.

5. A client is receiving oxygen therapy via a nasal cannula. The nurse should explain that this method of oxygen delivery does which of the following?

• A. Delivers a specific concentration of oxygen constantly
• B. Delivers a high concentration of oxygen
• C. Delivers a low concentration of oxygen
• D. Restricts the client's ability to eat, speak, or drink

Correct answer: A

Rationale: A nasal cannula is a device used for delivering supplemental oxygen to patients. It delivers a specific concentration of oxygen constantly, typically ranging from 1-6 liters per minute. This method is effective for patients who require low to moderate levels of oxygen. Choices B and C are incorrect because a nasal cannula does not deliver a high concentration of oxygen and is not considered a low concentration delivery method. Choice D is incorrect because a nasal cannula does not restrict the client's ability to eat, speak, or drink; it allows them to perform these activities while receiving oxygen therapy.
